How does co-op play?

Recordings of groups of two to four show:

• One apartment, shared supplies. The food and water on the racks belong to the group, and everyone’s eating draws from them. Agree on the ration level (food).
• Split the day 0 jobs. One person fills buckets while another gathers food; the objectives complete for the group.
• Heavy work goes faster with two. One solo player noted that dragging furniture out of a blocked doorway “would go by faster with two”.
• Friendly bumping is real. Players can push each other, and one got shoved out into the hallway during a break-in.
• Talk outside the game. There is no in-game voice chat, so the co-op groups we watched were on a call together.

One guide sums it up: solo it feels like a horror game, with friends it turns into screaming at each other over who forgot the wrench.

Good roles for a group

• Quartermaster: keeps water and food on the racks and watches the ration days.
• Door: checks the peephole, handles the chain and the barricade.
• Runner: carries the tools and does the vent and shaft trips (vents).
• Second runner or lookout for the fourth player.

These are suggestions built from the jobs the game hands out, not roles the game assigns.

Solo or co-op?

	Solo	Co-op (2–4)
Water and food	Last longest	Drain two to four times as fast
Day 0	Every objective yourself	Split between players
Fights	One weapon; step back and repeat	More hands, but players get in each other’s way and push each other
Heavy furniture	Slow	Faster with two
Mood	“An intense horror experience” (one guide)	Loud and chaotic

Tips from co-op recordings

• Pick a door person. The co-op run that ended worst started with two players arguing at the door during a break-in.
• Do not grab the bed someone else picked. Small, but it led to a fight in one run; agree on sleeping places on night 0.
• Read the commands. One group lost its doorway to a table because a player pressed a push prompt mid-conversation.

How do friends join your run?

In the co-op recording we watched, one player started the game first and the others could not join until it was ready (“it does not let me join… because I haven’t made it yet… it’s ready”). So the host sets up the run (saved game, see how to play) and friends join after. Whether a friend can drop into a saved run on a later day has not been shown.
